Abstract
Due to the increasing use of private cars for urbanization and urban transport, the travel time of urban transportation is increasing. People spend a lot of time in the streets, and the queue length of waiting increases accordingly; this has direct effects on fuel consumption too. Traffic flow forecasts and traffic light schedules were studied separately in the urban traffic system. This paper presents a new stable TS (Takagi–Sugeno) fuzzy controller for urban traffic. The state-space dynamics are utilized to formulate both the vehicle’s average waiting time at an isolated intersection and the length of queues. A fuzzy intelligent controller is designed for light control based upon the length of the queue, and eventually, the system’s stability is proved using the Lyapunov theorem. Moreover, the input variables are the length of queue and number of input or output vehicles from each lane. The simulation results describe the appearance of the proposed controller. An illustrative example is also given to show the proposed method’s effectiveness; the suggested method is more efficient than both the conventional fuzzy traffic controllers and the fixed time controller.
Highlights
It is assumed that T = 6(s) is a sampling time. α shows values in traffic conditions. Regarding this Table, we can see different traffic conditions in the urban traffic for i = 1, 2, 3, 4; the α parameter is between 0 and 1 so that its variations conform to Table 4
A fuzzy model of an urban traffic network was designed for a single intersection
The effectiveness of the suggested controller is verified by simulation results
Summary
One of the biggest issues in the world is urban traffic and transportation between cities. More than a million people spend a lot of time in traffic every day, and the total time wasted in traffic reaches millions of hours. Another disadvantage of traffic is air pollution. Urban traffic has three main factors: human, road, and vehicle. If none of these factors are present, urban traffic is not be generated. Traffic became one of the most critical factors disrupting urban transportation. When the flow is smooth, fast, and without significant environmental impact, the city has good traffic. An example of the essential characteristics of developed cities is the permanent population extension in a comparatively short region
